VALVE.

Application med-November 3, 1922. Serial No. 598,938.

To all 'io/wm t may. concern.'

Be itknown thatl, OswALo L. FiLLMonn, a: citizen of. the,L United. States, residing` at` llarriman, in the county of` Roanie and State of Tennessee, have invented=new and=use tul Improvements 11i-Valves, otwhich the.

tion being toiprovide compressed air for i forcingthe gasoline tromthe supply tank to the transparentchamber ot' the pedestal.

Another object of the invention is to provide a single valve for controlling the ilow ot gasoline into the said chamber and the passage of the surplus gasoline from the said chamber back to the supply tank as well as to control the flow of air.

Another object of the invention is to provide an auxiliary tank which is kept filled from the main tank under the action of gravity and to which the air supply is connected.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, il-

lustrated in the accompanying drawings,

and specifically pointed out in the appended claim.

In describing my invention in detail., reterence will be had to the accompanying dra-wings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a diagrammatic view of the system.

Figure 2 is a plan view of the valve.

Figure 3 is a. bottom plan view with the connectingpipes in section.

Figure l is a top plan view with theV coverremoved.

FigureI 5 is a longitudinal sectional view through the valve.

In these views 1 indicates the supply tank, 2 the auxiliary tank which is connected by the pipe 3 with the main tank in such a manner that it will be kept filled with gasoline under the action of gravity. A check valve 4 is arranged in the pipe 3. The pedestal is shown at 5 and said pedestal is preferably provided with the chamber 6, the walls ot which are formed of transparent material. A valve casing 7 is arranged in the base of the pedestal and a pipe 8 has one end connected with the top of said casing and the top ott-his pipe `is located in the-chamber (3. A'- pipe 9 connects thcbettom ofthe casing with the auxiliary` tank 2 and a pipe 1() connects the bottom of the casing with the main tank 1; Anair pipe lllconneets the bottom ci:A the casing;with

the auxiliary tank 2 andapipe12 connects the bottom ot the casing. witlra tank 13 which contains a supply Yof compressed air.

Meindicates a. vent pipe which is. connected witl-r the. bottom` of ithe. casing. Ai valve.. disci 15- is` varranged in the. casing. and `1s ground@ to make a tight fit with the bottom thereof. The valve disc is held on its seat by a spring 1G. The. stem 17 the valve disc passes through the top of the casing and is connected with a handle 18. The disc is provided With a port 19 which passes entirely through the disc and with passages 2O and 21 which are arranged in the lower face o1 the disc. A valve 22 is arranged in the pipe 12 and the parts of this valve are so arranged that it will be operated bv the handle 18 when said handle is moved in one direction. Stops 22 are located on the top of the casing for limiting the movement of the handle..

lVhen the chamber 6 is to be iilled with gasoline the handle 18 is moved to the left in Figure 2 so as to place the port 19 in the disc valve over the pipe 9 and to place the passage 21 in a position to connect the pipes 12 and 11. This movement of the handle will also open valve 22. rfhus air will How from the tank 13 through the pipe 12, across the passage 21 and through the pipe 11 into the tank 2. This compressed air will force the gasoline from the tank 2 through the pipe 9, into the valve casing through the port 19 and from the casing the gasoline will pass through the pipe 8 into the chamber 6. When the chamber is lilled the handle is moved to its first position so as to place the port 19 over the pipe 10 so that the surplus gasoline in the chamber G can How back into the tank 1. This surplus gasoline will flow back through the pipe 8 into the valve casing through the port 19and through the pipe 10 and thus return to the tank 1. At the same time the passage 20 is placed in position to connect the pipe 11 with the vent pipe 14 so that the air in the auxiliary tank 2 can escape and thus permit the tank to be refilled from the. main tank. The valve 22 will close as soon as it is disengaged by the handle.

From the above it willbe seen that the disc valve 15 controls the passage of air into the auxiliary tank and the escape or this air therefrom and it also controls the flow of gasoline from the auxiliary tank into the chamber 6 and the return of the surplus gasoline in chamber 6 to the main tank.

It is thought from the foregoing description that the advantages and novel features of my invention will e readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall With in the scope of the appended cla-im.

Ihat I claim is An apparatus of the class described cour prising a main tank, an auxiliary tank arranged to be filled from the main tank un der the action of gravity, a delivery chamher, a valve casing, a pipe connecting the same With the upper part of the delivery chamber, a pipe connecting the casing with the auxiliary tank, a pipe connecting the casing with the main tank, an air tank, a pipe connecting the saine With the valve casing, an air pipe connecting the valve casing with the auxiliary tank, a vent pipe connected with the valve casing, a valve in the casing having a port therein for connecting the delivery pipe with either the .pipe leading to the auxiliary tank or with the main tank and also having passages therein for connecting the air tank with the auxiliary tank or the auxiliary tank with the vent pipe, a handle for operating tho valve and a valve for controlling the flow of air from the air tank into the casing, said valve being` operated by the handle.

In testimony whereof I ailix my signature.
